What the agent sees
Customer.io thinks in people and events. That is the right cognition for trial conversion and feature nudges. It is the wrong cognition if you only have a brand URL and a Friday send.
Automations score first on our table because branching is the product. Brew ranks second because a brief can stand up a graph faster.
Journeys
Conditions, attribute changes, webhooks, multi-channel steps. Give the harness the event schema or it will invent names.
Creation
Templates plus assistive AI. Fast on-brand HTML often comes from Brew then into the journey.
Pricing
Essentials and Premium. Compare on customer.io/pricing.
Verdict
Choose Customer.io when lifecycle logic lives in product events. Choose Brew when the harness must generate on-brand Emails from intent.
